Morphometric analysis using remote sensing (RS) and geographical information system (GIS), in the recent study, has become an efficient method in the assessment of groundwater potential of a river basin. The present study focused on the morphometric analysis of Makaluva basin of Swarnamukhi river using RS and GIS techniques in the identification of groundwater potential zones for effective planning and management of groundwater resources of the basin. The study area was divided into four sub basins for the purpose of micro-level morphometric analysis. The main stream of the basin is of fourth order and drainage patterns of sub basins are mostly of dendritic and parallel type. Based on the linear, areal and relief parameters of sub basins, the groundwater potential zones of the basin were identified and the results substantiated with geomorphology map derived from RS data. The elongated shape, favorable drainage network, permeable geologic formation and low relief of the sub basins W1 and W4 make them the promising groundwater potential zones of Makaluva Basin of Swarnamukhi River. The statistical analysis and overlay analysis of the morphometric parameters also indicated the sub basins W1 and W4 as high groundwater potential zones. The thematic maps of Geomorphology, LULC, Soil, and Slope were converted to raster format and reclassified with 1 to 4 scale, representing poor, moderate, good, and very good zones of Groundwater potential. The groundwater potential map shows prioritized sub-basins and results are comparable with the compact factor analysis. The groundwater potential map supports the statistical analysis indicating the presence of groundwater potential zones in W1 and W4 sub basins.
